Abstract
Abstract A tapper to be driven into a substantially rigid mass by a power gun for the extraction of fluid therefrom and having a longitudinal body of cylindrical section including transverse and longitudinal fluid passages. A stop collar limits the forward movement of the tapper and a rearwardly disposed pull ring, defines, with the stop collar, a groove for supporting a collection container and permitting reception of a removal tool.

Independent Claim

A tapper of unitary construction having a longitudinal body including a cylindrical forward body section, a conical driving point at the free end of said forward body section, a radially outwardly directed circumferentially extending collar on said longitudinal body at the rear of said forward body section, a radially outwardly directed circumferentially extending pull ring on said longitudinal body spaced rearwardly of said collar and being of substantially the same dimension as said collar, said collar and said ring defining a groove therebetween of arcuate cross section substantially complementary to the cross section of a bucket hanger received therein, a substantially cylindrical impact head at the rear oF said body extending rearwardly of said pull ring, said impact head having a length at least approximately one-half the length of said forward body section and having substantially the same outer diameter as said forward body section, said impact head having a wall thickness and being of a construction so that it is adapted to receive repeated blows sufficient to embed the tapper to a desired depth in a means such as a tree, said impact head having the outer surface thereof roughened and receiving a drain hose thereover for retaining the drain hose in operative position, a central fluid-collecting chamber formed within said body and extending rearwardly from said forward body section adjacent said driving point and opening through the rear of said impact head, said forward body section being provided with a pair of elongated transverse slots extending through the major part of the longitudinal length of said forward body section and being in communication with said chamber, said slots being disposed diametrically opposite one another and having a height less than the diameter of said chamber.
